Bcr-Abl

Combinational treatment of kinase inhibitors induces the similar phenotype produced by PP1. All images are lateral view with dorsal to the top and anterior to the left. The combinational treatment of Dasatinib (D) or U0126 (U) with Sunitinib (SU),PTK787 (PTK), or ZM323881 (Z) resulted in the shrinkage of dorsal aorta.

THOC5 phospho-Y225 levels were assessed in the populations shown by flow cytometry following 24 h treatment with 5 μM imatinib, 150 nM dasatinib or 5 μM nilotinib. Results are displayed as mean fluorescence intensity (n= 4) ±s.e.m.

Senescence induction upon PKCι depletion combined with aurora kinase inhibition. ( a) MCF7 cells were transfected as above to deplete PKCι . Two days after transfection, cells were treated for the indicated time period with 400 n M VX-680. Medium with VX-680 was then removed and fresh medium was added. Cells were stained for SA-b -gal activity 5 days after the start of transfection.* indicates a P value <0.05. ( b) MCF7 cells were treated as above. Five days after transfection, cells were fixed and assessed for the presence of gH2AX foci by immunofluorescence microscopy. (c, d) MCF7 cells were treated with dimethyl sulfoxide (DMSO) control or 400 n M VX-680 for the indicated time periods. Total cell lysates were then analyzed by western blotting for levels of p21 and GAPDH (as loading control). A representative blot is shown in panel c. Quantitation of changes in p21 levels (normalized to vehicle-treated controls) is shown in panel d. The data shown are the means ±s.e. of three independent experiments.

Inhibition of thymidine (a and b) and cytarabine (c and d) uptake with imatinib. K562 cells (a and c) and MEG-01 cells (b and d) were incubated at 37 ◦C for 15 min with imatinib transport buffer, and then incubated with 0.5 Ci of [3H] thymidine or [3H] cytarabine for an additional 5 min in presence of imatinib. Cells were then washed 3 times, lysed and radioactivity associated to cell pellets was quantified. DMSO, dimethylsulfoxide; DPD, dipyridamole.

Effect of nilotinib on Bcr-Abl kinase activity in ABCB1- and ABCG2- overexpressing CD34⁺CD38^- cells. K562 parental cells and CD34⁺CD38^- subpopulation isolated from K562 cells were treated with nilotinib at 0.01, 0.1 and 1.0 umol/L for 12 h. Equal amount of protein was loaded for western blot analysis as described in the Experimental section. The experiments were repeated at least three times independently, and a representative experiment is shown.

A,IC50 of Bosutinib that block ANDV-induced EC permeability. Endothelial cells were ANDV infected, and 3 days postinfection the permeability of cells in response to VEGF addition was determined in the presence or absence of increasing amounts of kinase inhibitor. The effect of inhibitors is presented as the percentage of ANDV-induced permeability of inhibitor-treated monolayers 3 days postinfection and 30 min post-VEGF and FITC-dextran addition. B, VEGFR2-Src inhibitors block ANDV-induced permeability. Endothelial cells were plated on vitronectin-coated Transwell inserts and infected at an MOI of 0.5 in triplicate with ANDV. Three days postinfection, the permeability of ANDV- and mock-infected endothelial cell monolayers was determined as described for Fig. 1 at indicated times in the presence or absence of Bosutinib .

Western blot analysis of p-histone and histone. 0-10μM KW2449 was added.

A, HeLa cells were treated with DMSO, Taxol (100 nM for 16 h), or Nocodazole (Noco, 100 ng/ml for 16 h). Total cell lysates were probed with the indicated antibodies against Hippo components on Phos-tag SDS-polyacrylamide gels. O and * mark the non-phosphorylated and phosphorylated proteins, respectively.

B. Western blot analysis of phosphorylated Akt, S6 and CrkL in T-ALL cell lines treated for 4 h with 2 μM Imatinib or Nilotinib or 0.1 μM GZD824. Twenty-five μg of protein were blotted to each lane. β-Actin documented equal lane loading. Imatinib, Nilotinib and GZD824 were abbreviated in IMA, NIL and GZD.

Combinational treatment of kinase inhibitors induces the similar phenotype produced by PP1. All images are lateral view with dorsal to the top and anterior to the left. The combinational treatment of Dasatinib (D) or U0126 (U) with Sunitinib (SU),PTK787 (PTK), or ZM323881 (Z) resulted in the shrinkage of dorsal aorta.
